Oral cavity and pharyngeal cancer has been well recognized as a public health problem. Prognosis for oral cancer is substantially improved when diagnosed early. A study was made of the impact of different educational strategies upon knowledge of oral cancer, evaluating the intervention after 4 weeks.
Ninety subjects over 40 years of age were consecutively included and randomized to three different groups (video, leaflet, verbal information). All subjects completed a 20-item pre-test on their knowledge of the risk factors, signs, and symptoms of oral cancer, and posteriorly received the video, leaflet, or verbal information, with evaluation of the results after 4 weeks.
In relation to the items correctly answered at baseline, all subjects showed an increase in knowledge score after 4 weeks: verbal information 4.77 ± 3.31, leaflets 4.53 ± 3.44, and video 3.67 ± 3.31 – no statistically significant differences being observed for any of the three strategies.
The oral cancer knowledge score increased following the educational intervention, which proved successful over the short term. Copyright © 2012 John Wiley & Sons, Ltd.
